Can Large Rivers Be Restored?Most restoration projects are only attempts to rehabilitate selected river sections to a predetermined structure and functio

摘要: Riverine ecosystems are remarkably resilient in their ability to recover from physical and chemical disturbances. If the disturbance occurs as a pulse, ecosystems`s original condition often occurs. However, if is sustained causes complete loss of critical habitat elements, ecological integrity cannot be maintained. Because running water so intimately tired physical, chemical, biological processes that occur throughout catchment restoration complex difficult task. Restoration rehabilitation projects on small streams rivers have been common practice for many years; however, large river systems far less common, there little predict success or monitor recovery. Renewal interactions between main channel, backwaters, flood plains central rehabilitation. This article discusses following topics some detail: River channel manipulations; Backwater treatments; riparian zone floodplain alterations; flow regulation; predicting recovery rates. 66 refs., 6 figs. 2 tabs.
